CAMERA-TRIPOD.

Specification of Letters Patent.

Application filed March 26, 1909. Serial No. 486,002. A

To all whom it may concern:

Be it known that I, InvIN l/V. BOESHANS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Camera-Tripods, of

a which the following is a specification.

. The invention relates to an improvement in camera tripods, and is particularly directed' to a means for securing the camera to the tr1pod in a manner to permlt theconvenl'ent posltionlng of the camera and the fixed securing of the camera in the desired position without moving the tripod.

The main object of the present invention is the provision of a camera engaging means carried by the tripod and normally arranged for free rotary movement on the tri-.

pod while fixed to the camera, whereby when the camera is in position it may be adjustthe camera base, the securing plate, the tripod head and the thumb nut for fixlng the plate to the head. Fig. 3 is a plan of the securing plate.

Referring particularly to the accompanylng drawings, 1 1s a camera head, preterably of the usual circular form in plan having depending ears 2 arranged in pairs, between whichthe camera legs 3 are pivotally mounted. Aside from the details to be hereinafter noted the form of the tripod is immaterial so far as the present invention is concerned, for which reason I contemplate the use of camera legs of telescopic or any other form connected to the plate in any desired manner.

For the purposes of the present invention the-head plate 1 is'provided with an upwardly extending centrally arranged off-set 4-, forming a supporting base for the securing p'l'at'e, as will be hereinafter explained.

The essential feature 01? the present invention resides in a securing plate 5 preferably an. integral body having a central portion 6 of the maximum diameter, the peripheral edge of which is roughened to provide for convenient manipulation. On the lower portion of the operating disk 6 is secured a dependin centrally arranged circular plate or spaclng disk 7, which, when the securing plate is in position, is designed to rest upon the supporting base 4, the plate 7 corresponding in diameter to that of the base 4. On the upper surface of the operating disk 6 there is secured an upwardly extending centrally arranged track 8 forming a camera support. This track has a diameter slightly exceeding that of the plate 7, to insure a more effective securing of the camera thereto.

The securing plate is provided with upwardly and downwardly extending threaded plugs 10 and 11, the former being designed to engage a threaded socket 12 secured in the camera base 13 and the latter passing through an opening 14 in the supporting plate at and head plate 1 of the tripod, projecting below the head plate to be engaged by an elongated thumb screw 15.

In use it is obvious that with the tripod in set position the camera is free to be rotated in position in a horizontal plane by loosening the thumb nut 15, and then fixed in the desired position by tightening the thumb screw. As will'be apparent from Fig. 1 of the drawings, the adjustment and fixing of the camera with relation to the tripod may be readily accomplished without disturbing the tripods adjustment, thereby conveniently adapting thedevice fortaki'nga number of pictures of different pointslfrom the same tripod position. The adjustment of the camera with relation to the tripod after loosening the thumb nut 15 may be readily accom;

plished by manipulation of themill'ed di'sk' 6, as will be obvious, the provision ofthe plates 7 and 8 spacing the camera from the --head plate of the tripod to permit such operation.

Having thus described the invention what I claim as new, is v A device of the class described including a circular body, a depending circular exten sion formed on the under side of said body and having a diameter smaller than that of the body, an annular track formed on the upper side of the body and having adi ameter smaller than that of the body, that portion of the body projecting beyond the track and extension forming a manipulating member, a threaded plug formed on and depending from the under side of said extension, and a threaded plug formed on and rising vertically from the body, said last named plug being arranged centrally of the IRVIN- W. BOESHANS.
